In high temperatures, be cautious of electrical fires posing a threat. Due to the persistent heat, electricity consumption in households increases sharply. For home fire prevention, electrical fires become the most significant threat among fires during the summer; therefore, it is essential to raise awareness of fire safety and take precautions against electrical fires. So what is an electrical fire? How should we prevent it? Now, the fire officers will share with you some basic knowledge about electrical fires. An electrical fire refers to a disaster caused by combustion resulting from electrical factors, and it accounts for a large proportion of fire accidents. In addition to causing injuries and equipment damage, electrical fires can also lead to power outages in electrical systems, resulting in significant losses for the national economy. Therefore, preventing electrical fires is one of the important aspects of safety work. Preventing household electrical fires: 1. Do not purchase products without proper certification or quality assurance. Electrical equipment should be installed and repaired by qualified electricians. II. Consciously abide by the rules and regulations regarding safe electricity use; it is prohibited to pull wires privately or install electric stoves without authorization. When checking and repairing household appliances, the power supply must be turned off first. III. When using household appliances, there should be complete and reliable power cord plugs. If the power cable is damaged, it must be replaced immediately or wrapped securely with insulating cloth. IV. The electrical wiring should not be too long; the lamp holder should be at a height of no less than 2 meters above the ground. It should be fixed in one place and not moved around, to avoid electric shock accidents. V. The fuse should be selected based on the wattage of the electrical equipment; do not change the fuse specifications on your own just because of high electricity consumption in summer. If fuses blow frequently, a qualified electrician should identify the cause and resolve the issue. VI. Do not pull wires randomly or connect them improperly, and do not move electrical equipment casually. Switches and fuses must not be installed on the ground wire and neutral wire. It is prohibited to connect the grounding wire to water supply or gas pipelines. Do not place the wire used for drying clothes near electrical wires, to prevent the wire from coming into contact with them; also, do not dry clothes or hang items on electrical wires. It is also necessary to prevent plants grown at home, such as vines and trees, from coming into contact with electrical wires. VII. Teach children not to play with electrical devices such as wires, light bulbs, switches, and motors. Parents should remind their children not to play near electric motors or transformers, and not to fly kites near electrical wires. If a kite ends up on a wire, it should be handled by an electrician; one should not pull hard on it themselves, as this could cause the wires to touch each other and lead to power outages or electric shock accidents. 8. After moving electrical devices with metal casings such as refrigerators to a new location, it is necessary to install the grounding wires first, and then inspect the devices. Only after confirming that there are no issues with them can they be put into use. 9. Do not touch electrical equipment with wet hands, and do not wipe electrical equipment with a wet cloth. Do not move charged objects on wet surfaces or wipe charged household appliances with a wet cloth to avoid electric shock. X. Turn off the main power switch when away from home for an extended period of time. Prevention alone is not enough; it is also necessary to learn how to extinguish electrical fires at home and possess first-aid knowledge. I. How to extinguish a fire: When there is a fire involving electrical appliances or wires, the power supply should be turned off first before attempting to put out the fire. If a fire breaks out due to a short circuit in a single appliance, the power switch for that appliance can be turned off immediately to cut off the power supply. If the entire circuit catches fire, the main switch must be turned off to cut off the power supply. If it is too far from the main switch and there is no time to turn it off, decisive action must be taken to cut the wires that are far from the fire site using the correct method. If it is not possible to cut off the power supply and firefighting must be carried out while the electricity is still connected, the following two points must be observed: 1. Be careful not to pull or cut the wires with your hands or metal tools; instead, stand on a wooden stool and use tools such as wire cutters or pliers with insulated handles to cut the wires. 2. When electrical equipment catches fire, it cannot be extinguished by pouring water directly on it. Since water is conductive, entering charged equipment can easily lead to electric shock, reduce the insulation properties of the equipment, and even cause the equipment to explode, posing a threat to human safety. After a fire breaks out in oil-filled equipment such as transformers and oil circuit breakers, water can be sprayed in a mist form to extinguish the fire. Due to the large area of water mist and small water droplets, they absorb heat easily and vaporize, rapidly lowering the flame temperature. II. How to provide first aid to someone who has been electrocuted 1. When you notice that someone has been electrocuted, first help them get away from the power source as quickly as possible. Never try to pull the affected person with your hands; instead, turn off the switch to cut off the power supply, or use a dry wooden stick or bamboo pole to move the wires aside, or employ a tool with an insulated handle to cut the wires. 2. Quickly move the person who has been electrocuted and is no longer connected to the power source to a well-ventilated, dry area where they can lie on their back. Loosen their shirt and belt, check whether they are breathing, and feel for a pulse in their carotid artery. 3. In case of an emergency, perform first aid using correct techniques of artificial respiration and chest compressions, and at the same time call the emergency number 120 to have medical personnel arrive at the scene as soon as possible to provide treatment. Until the medical staff arrive, those present should not give up trying to save the victim.
